Web server plug-in request and response optimization properties

Use this page to view or change the request and response optimization properties for a Web server plug-in.

To view this administrative console page, click Servers > Web Servers > web_server_name Plug-in Properties > Request and Response.

Enable Nagle Algorithm for the IIS Web Server

When checked, the Nagle algorithm is used for connections from the Microsoft Internet Informations Services (IIS) Web Server to the Application Server.

This field corresponds to the IISDisableNagle element in the plugin-cfg.xml file. It only applies if you are using the Microsoft Internet Informations Services (IIS) Web server.

By default, this field is not checked, and the Nagle algorithm is disabled. Select this field to enable the Nagle algorithm for this connection.

Chunk HTTP response to the client

When checked, responses to the client are broken into chunks if a Transfer-Encoding : Chunked response header is present in the response.

This field corresponds to the ChunkedResponse element in the plugin-cfg.xml file. It only applies if you are using a Microsoft Internet Informations Services (IIS) Web Server, a Java System Web server, or a Domino Web server. The IBM HTTP Server automatically handles breaking the response into chunks to send to the client.

By default, this field is not checked, and responses are not broken into chunks. Select this field to enable responses to the client to be broken into chunks if a Transfer-Encoding : Chunked response header is present in the response.

Accept content for all requests

This field corresponds to the AcceptAllContent element in the plugin-cfg.xml file.

When selected, you can include content in GET, and HEAD requests when a Content-Length or Transfer-encoding header is contained in the request header.

By default, this field is not checked. Select this field to enable users to include content in GET, and HEAD requests when a Content-Length or Transfer-encoding header is contained in the request header.

Virtual host matching

When selected, virtual host mapping is performed by physically using the port number for which the request was received.

This field corresponds to the VHostMatchingCompat element in the plugin-cfg.xml file.

By default, this field is not checked, and matching is done logically using the port number contained in the host header. Select this field if you want virtual host mapping performed by physically using the port number for which the request was received.

Use the radio buttons to make your physical or logical port selection.

Application server port preference

Specifies which port number the Application Server should use to build URIs for a sendRedirect. This field is only applicable for a sendRedirect if you use relative URIs and does not affect absolute redirects. This field also specifies where to retrieve the value for HttpServletRequest.getServerPort().

This field corresponds to the AppServerPortPreference element in the plugin-cfg.xml file.

Specify: The default is hostHeader.

Priority used by the IIS Web server when loading the plug-in configuration file

Specifies the priority in which the Microsoft Internet Informations Services (IIS) Web server loads the WebSphere Web server plug-in.

This field corresponds to the IISPluginPriority element in the plugin-cfg.xml file. It only appears if you are using the IIS Web server. Because the IIS Web server uses this value during startup, the Web server must be restarted before a change to this field takes effect.

Select one of the following priorities:

The default value of High ensures that all requests are handled by the Web server plug-in before they are handled by any other filter/extensions. If problems occur while using a priority of Medium or Low, you will have to rearrange the order or change the priority of the interfering filter/extension.
